PENN, OF SHERMAN, TEXAS.

GAS GENERATOR AND BURNER.

Specification of Letters Patent.

Patented Mar. 23, 1915.

Application filed December 11, 1914. Serial No. 876,630.

To all whom it may concern Be it known that 1, JAMES F. HOPPER, acitizen of the United States, residing at Sherman, in the county ofGrayson and State of Texas, have invented certain new and useful.Improvements in Gas Generators and Burners, of which the following is aspecification.

My invention relatesto a combined gas generator and burner, and itparticularly relates to a device of this character adapted to be used inconnection with ordinary cooking and heating stoves, kitchen-ranges,&c., for burning kerosene oil, but also adapted for other uses.

An object of the invention is to provlde a device of this characterwhich may be fitted into the firebox and located above the grate ofstoves of diiferent sizes, or having different sized fireboxes, withequal efiiciency.

Another object and essential characteristic feature of the invention isto provide a device of this character having a return pipe extendingfrom the gas generating coil to, and communicating with the top of theoil supply tank, into which tank any excess of gas generated in the coilwhen in operation is conducted and it attains considerable pressure;causing a torch-like flame beneath the coil and thereby assistingcombustion, giving the device a greater breadth of utility andadaptation.

A still further object is to provide a fuel supply tank communicatingwith both the liquid supply pipe and the gas inlet p pe and having anovel arrangement insuring the filling of the tank only to apredetermined point, leaving space above the oil for the receipt of gaswhen the burner is in use, and also, after the burner has first beenused the supply of gas retained in the tank enables the burner readilystarted and heated when gas will again be generated.

Other objects and advantages will be hereinafter set forth and also toacquire a knowledge of the details of construction and means foreffecting the results reference is to be had to the followingdescription and draw: ings hereto attached. I r

In the accompanying drawings which are made a part of thisspecification, Figure 1, represents a front elevation of a stove w ththe burner applied and having a section broken out through which theburner may be seen, and Fig. 2 is a plan view of the same.

Referring more particularly to the drawings in which similar referencenumerals designate corresponding parts throughout the several views, thedifferent structural features of the burner are preferably substantiallyas hereinafter described. HOW- ever, they are susceptible to a greateror less degree of modification with reference to the spirit of theinvention.

In the drawings, the numeral 1 indicates a stove of ordinaryconstruction; 2 the usual fire box in which is located the gasgenerating pipes which comprise a combined horizontally disposedsuperheating coil 3, located at one end and near the top of the firebox;from the outer convolution of this coil a pipe 4 extends to near theopposite end of the box and is there connected by a transverselydisposed loop 5 to a downwardlyinclined pipe 6, that extends back to andthrough the end of the box and is connected. by a laterally disposedpipe 7 to a burner pipe 8, that enters the box and extends centrallybeneath the coil to near the opposite end of the box, and thence upwardand back again through the box, to and connected near the top of an oiltank 9. Centrally lo.- cated in the pipe 7 is a T, 10, provided with anangle valve 11 to which is connected an auxiliary burner pipe 12, closedat one end, that supplies gas to another burner supported thereby, whendesired. From the inner convolution of the coil and connected in anyusual manner to the bottom of the storage tank 9 is the oil supply orinlet pipe 13, provided with the usual controlling-valve 14, from whichtank the supply of oil used with the present burner is taken.

The burner pipe 8 has a small perforation or jet on the top side at 15where the oil is ignited, and the pipe 12 has a similar jet at 16. 17and 18 are draft tubes and mixing chambers, they are apertured at theirbase and vertically supported on the respective pipes in any convenientmanner. Perforations 19 are provided for the passage of air within thetubes. Secured to the generator pipe 8, by any proper means such as, forinstance, eye bolts 20, are deflectors or spreaders 21, centrallylocated over the gas jets and adapted to spread the flame when the gasfrom the jets is burning.

The closed top of the oil tank 9 is perforated and provided with a tube22, that extends dow" some distance within it, also a slight distanceabove the top of same, where it is closed by a cork 3; the tank issupplied with oil through this tube and its function is to prevent thetank being entirely filled with oil, thus insuring a chamber for gaswhen the burners are started. The pipe 8 is forked before entering thetank and communicates with it at two points, 2% and 25; the formerhaving an automatic check valve 26 entering in the tank, and the lattera throttle valve 27, for regulating the outlet of gas as required.

in operation, liquid fuel passes from the supply tank through the supplypipe 13, and the quantity thereof is regulated by the valve 1%; the oilcontinues its course through the coil and other pipes and flows throughthe perforations 1-5 and ignited, thereby heating the coil and pipesections to such an extent that the gas is quickly generated within thepipes, when the burning of the gas from the jets keeps the coil andpipes continually hot enough to continue the generation of the gas solong as fuel is admitted through the pipe. After starting the firstburner, should more heat be required, the valve 11 may be opened and gasadmitted to the jet 16, thus operating both burners. ithen more gas isenerated than is consumed by the ets, it flows around and back throughthe pipes and enters the vacant portion within the tank through thecheck valve 26, attaining desired density therein; and the same pressurebeing maintained in the pipes, exerts considerable force upon theburning jets; producing a torch-like flame of intense heat, also aperfect combustion which thoroughly utilizes all of the heat propertiescontained in the oil. When the operation of the burners is no longerrequired, the valves 1% and 2'? are closed, when suliicient gas will beretained in the tank to again start them Without the necessity of firstflowing oil to the jets.

ll hat I claim is 1. In a gas generator and burner for stoves and thelike, a tank, an oil supply pipe and generator pipes, the oil supplypipe connected with the bottom or" the oil supply tank, and one of thegenerator pipes having a jet opening therein, and said generator pipeextended to the top of the tank and connected thereto at two pointsforking therefrom, one of the said connections being provided with aninlet check valve, and the other with a throttle valve, tor the purposespecified.

The combination with a stove of a gas generator and burner, an oilsupply tank apertured through the top and provided with a tube extendingsome distance downward Within it, and above the same to receive a cork,a generating coil and generating pipes located within the firebox 035said stove and an oil supply pipe opening in the bottom of the tank andextending to said coil, and said generating pipes communicating withsaid coil and passing out of the box and to the top of the tank where itbranches, entering the tank at two points; one of said branches beingprovided with a check valve and the other with a throttle, as and forthe purpose specified.

In testimony whereof l afiix my signature in presence of two witnesses.
